This is how the collector motor works.
So the brushless three-phase motor works.
You can easily find a detailed description of the principle of operation of a brushless three-phase motor, so I will not do this.
The designs of motors can have different numbers of magnets and coils,
but the principle is the same: the number of coils is a multiple of three and the number of magnets is a multiple of two.
I tried to make a motor model of the simplest option: three coils and two magnets.
If you want to repeat this project, be sure to wrap the magnets with 5-10 layers of thick fiberglass and soak it well with epoxy.
Any other materials and adhesives will explode the high RPM centrifugal force, magnets will fly away and may injure you!
Observe precautions!
Make protective shields and do not stand close to the rotating open rotor with high RPM, this is dangerous!
I am trying to increase the RPM with a speed regulator and also with the voltage of the power supply,
but above 24,000 RPM the motor synchronization breaks.
For a higher RPM, the manufacture of all nodes at a higher level is required.
It should be completely different engineering solutions, other materials and high precision manufacturing.
I think you are interested to see how the industrial motor of this principle works.
I increase the speed with an electronic controller, then I increase the voltage of the power supply.
